Note: Used to give more information that is necessary in a given situation.

General safety instructions

WARNING: Read the warning instructions that follow before you use the product.

• This product is dangerous if used incorrectly or if you are not careful. Injury or death can occur if you do not obey the safety instructions.
• This product produces an electromagnetic field during operation. This field may under some circumstances interfere with active or passive medical implants. To reduce the risk of serious or fatal injury we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this product.
• Always be careful and use your common sense. If you are not sure how to operate the product in a special situation, stop and speak to your Husqvarna dealer before you continue.

• Keep in mind that the operator will be held responsible for accidents that involve other persons or their property.

• Keep the product clean. Make sure that you can clearly read signs and decals.

• Never allow children or people unfamiliar with these instructions to use the appliance. Local regulations may restrict the age of the operator
• Always monitor a person, with decreased physical capacity or mental capacity, that uses the product. A responsible adult must be there at all times.
• Do not use the product if you are tired, ill, or under the influence of alcohol, drugs or medicine. This has a negative effect on your vision, alertness, coordination and judgment.
• Do not use the product if it is defective.
• Do not change this product or use it if it is possible that it has been changed by others.

Work area safety

WARNING: Read the warning instructions that follow before you use the product.

- Remove objects such as branches, twigs and stones

from the work area before you use the product.

• Objects that hit against the dethatcher equipment can eject and cause damage to persons and objects. Keep bystanders and animals at a safe distance from the product.
• Never use the product in bad weather such as fog, rain, strong winds, intense cold and risk of lightning. To use the product in bad weather or in moist or wet locations is tiring. Bad weather can cause dangerous conditions, such as slippery surfaces.
• Look out for persons, objects and situations that can prevent safe operation of the product.
• Look out for obstacles, such as roots, stones, twigs, pits and ditches. Long grass can hide obstacles.
• To operate the product on slopes can be dangerous. Do not use the product on ground that slopes more than 15°.
• Operate the product across the face of slopes. Do not move up and down.
• Be careful when you go near hidden corners and objects that prevent a clear view.

Work safety

WARNING: Read the warning instructions that follow before you use the product.

• Use this product to remove thatch and moss from grass lawns only. It is not permitted to use it for other tasks.
• Use personal protective equipment. Refer to Personal protective equipment on page 14.
• Do not operate the product in rain or wet conditions. The risk of electrical shock increases if water enters the product.
• Do not operate the product unless the dethatcher equipment and all covers are attached correctly. An incorrectly attached dethatcher equipment can come loose and cause personal injury.

• Make sure that the dethatcher equipment does not hit objects such as stones and roots. This can do damage to the dethatcher equipment and bend the motor shaft. A bent axle causes heavy vibration and a very high risk that the dethatcher equipment becomes loose.

• If the dethatcher equipment hits an object or if vibrations occur, stop the product immediately. Stop the motor, turn the safety key to 0 and remove the battery (model S 138i) or disconnect the power cord (model S 138C). Examine the product for damages. Repair damages or let an authorised service agent do the repair.

• Never attach the motor brake handle permanently to the handle when the motor is started.
• Put the product on a stable, flat surface and start it. Make sure that the dethatcher equipment does not hit the ground or other objects.
  • Always stay behind the product when you operate it.
• Let all the wheels stay on the ground and keep 2 hands on the handle when you operate the product. Keep your hands and feet away from the rotating dethatcher equipment.
• Do not tilt the product when the motor is started.
• Be careful when you pull the product rearward.
• Never lift up the product when the motor is started. If you

must lift the product, first stop the motor, turn the safety key to 0 and remove the battery (model S 138i) or disconnect the power cord (model S 138C).

• Do not walk rearward when you operate the product.
• Stop the motor when you move across areas without grass, for example paths made of gravel, stone and asphalt.
• Do not run with the product when the motor is started. Always walk when you operate the product.
• Stop the motor before you change the work depth. Never make adjustments with the motor started.
• Never let the product stay out of view with the motor started. Stop the motor and make sure that the dethatcher equipment does not rotate.

Safety instructions for operation Personal protective equipment

You must use approved personal protective equipment whenever you use the product. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident

does happen. Ask your dealer for help in choosing the right equipment.

Always wear:

• Hearing protection to minimise the risk of hearing impairment.
• Sturdy, non-slip boots or shoes. Do not wear sandals or go barefoot.
• Heavy, long pants. Do not wear shorts.

Wear gloves when required, for example when fitting, inspecting or cleaning the dethatcher equipment.

WARNING: Use approved hearing protection. Long term exposure to noise can result in permanent hearing impairment.

Safety devices on the product

WARNING: Read the warning instructions that follow before you use the product.

• Do not use a product with defective safety devices.
• Do a check of the safety devices regularly. If the safety

devices are defective, speak to your Husqvarna service agent.

To do a check of the covers

The dethatcher cover decreases vibrations in the product and decreases the risk of injury from the dethatcher equipment.

• Examine the side dethatcher cover to make sure that there are no damages such as cracks.
• Examine the rear cover to make sure that there are no damages such as cracks.

Motor brake handle

The motor brake handle stops the motor. When the motor brake handle is released, the motor stops.

To do a check of the motor brake, start the motor and then release the motor brake handle. If the motor does not stop in 3 seconds, let an approved Husqvarna service agent adjust the motor brake.

(Fig. 27)

Safety key

The safety key is found below the battery lid. The safety key is

used to connect the battery that supplies the motor with power.

• Start and stop the motor to do a check of the safety key.
• If the safety key functions correctly, the motor starts only when the key is turned to 1.

(Fig. 28)

To examine the start inhibitor

Do a check of the start inhibitor to make sure that it prevents operation of the motor.

1. Push the motor brake handle in the direction of the handlebar. The start inhibitor stops the movement.
2. Push the start inhibitor out. (Fig. 29)
3. Release the start inhibitor and make sure that it goes back to its initial position.

To use the power cord holder (model S 138C)

The power cord holder decreases the strain on the power socket and the power cord. The power cord holder also decreases the risk that you fall.

1. Bend the power cord to a small loop.

2. Put the loop in to the hole in the power cord holder.

3. Put the loop around the hook.
4. Pull the power cord to tighten the loop around the hook. (Fig. 30)

sunlight. Do not charge the battery in wet conditions.

Power cord safety

For model S 138C.

• The use of a Residual Current Device (R.C.D.) with a tripping current of not more than 30mA is recommended. Even with an R.D.C. installed, 100% safety cannot be guaranteed and safe work procedures must be obeyed at all times. Do a check of your R.C.D. each time you use it.
• Immediately disconnect from the mains if the power cord is cut or the insulation is damaged.
• Do not touch a cut or damaged power cord until the electrical supply is disconnected.
• Do not repair a cut or damaged power cord. Replace it with a new one.
